Be careful when buying. They would recommend 1 1/4 nails that don't even fit. Please read the description first before purchasing. I sent mine back because I can't use it for what I need. It's just a stapler. This is NOT a nail puller. It is only suitable for very light stapling work on soft materials as thick as a piece of cardboard. The maximum bar size required is 5/8" and it won't even be able to drive it fully into most but the softest pine woods. It's no better with staples than with nails. very powerful If you want a real nailer, buy a pneumatic one.
